It was never explicitly stated whether or not the adults were expected to join in the singing and group large motor activities, but after a couple
sessions it was clear to me that the parents who sat and watched this
circle time tended to have the children who sat and watched, whereas those of us who jumped up and down and wiggled our fannies along with the teacher had children who participated.
Maybe there are people who attended training
sessions at the same
time you did who would like to be a member of your leadership
circle and help get the group started.
